Thanks, guys. The mini Talon sure flies like a rock so I can see why it is a popular choice for FPV.
My MT QuadPlane weighs about 5.6lbs (2.5kg). Both my 4s 6AH and 4s 8AH packs weigh about 22oz (623g).
Yes, the rocking in FBWA was the wind and thermals rising from the fields. It was about 80 degrees F outside.
I still need to get used to the plane and pull back the stick a bit on take-off and transition back to hover mode but they are still quite graceful. The MT scoots along nicely even with the added drag from the quad rotors.
I'll pull my logs today and get some numbers...
